Acesso em: 06 mar. 2015.2095-2686http://www.repositorio.ufop.br/handle/123456789/5100This paper presents three case studies comprising failure mechanisms in phyllite mine slopes at Quadrilátero Ferrífero, State of Minas Gerais, Brazil. Numerical modeling techniques were used in this study. Failure mechanisms involving discontinuities sub parallel to the main foliation are very common in these mines. Besides, failure through the rock material has also been observed due to the low strength of phyllitesin this site. Results of this work permitted to establish unknown geotechnical parameters which have significant influence in failure processes, like the in situ stress field and the discontinuity stiffness.pt-BRSoft rocksMine slopesNumerical modelingFailure mechanismsArtigo publicado em periodicoO periódico International Journal of Mining Science and Technology concede permissão para depósito deste artigo no Repositório Institucional da UFOP.
